Omaka abaningi be-RFID bakankulunkulu wethegi ye-RFID!
Kusukela ekushicilelweni Cishe sekudlule iminyaka engu-7. Kwalaba , inani elikhulu lamathegi e-RFID namakhadi ahlakaniphile anqwabelene emaphaketheni ami: amakhadi avikelekile (ngokwesibonelo, izimvume noma amakhadi asebhange), amaphasi e-ski, amaphasi ezithuthi zomphakathi, okuthi ngaphandle kwawo kwamanye eNetherlands akunakwenzeka ukuphila ngaphandle kwawo, bese kuba nokunye. .
Sekukonke, sekuyisikhathi sokulungisa yonke le nsizwa ethulwa ku-KDPV. Ochungechungeni olusha lwezihloko mayelana ne-RFID namakhadi ahlakaniphile, ngizoqhubeka nendaba ehlala isikhathi eside mayelana nemakethe, ubuchwepheshe kanye nesakhiwo sangaphakathi sangempela. micro-ama-chips, ngaphandle kwalokho impilo yethu yansuku zonke ayisacabangeki, kusukela ekulawuleni ukuhamba kwezimpahla (isibonelo, ) bese iphetha ngokwakhiwa kwezakhiwo eziphakeme. Ngaphezu kwalokho, ngalesi sikhathi abadlali abasha (isibonelo, amaShayina) bafikile ebhodini, ngaphezu kokukhathala okufanele sikhulume ngakho.
Njengenjwayelo, indaba izohlukaniswa ngezingxenye ezinezihloko, engizozithumela ngokwamandla ami, amakhono ami kanye nokufinyelela ezinsizakalweni.
Isibikezelo
Ngakho-ke, kuhle ukukhumbula ukuthi amamaki okuvula kimina kwakuwukuqhubeka komsebenzi wami wokuzilibazisa wokusebenza nge-electron microscopy kanye nokusika. emuva ngo-2012. IN Ithiyori yokusebenza kwamathegi e-RFID yabuyekezwa kafushane, futhi omaka abambalwa abavame kakhulu nabatholakalayo ngaleso sikhathi bavulwa futhi bahlakazwa.
Cishe kuncane okungangezwa kulesi sihloko namuhla: izindinganiso ezifanayo ezi-3(4) ezivame kakhulu LF (120-150 kHz), HF (13.65 MHz - iningi lamathegi asebenza kulobu bubanzi), UHF (eqinisweni, kunamafrikhwensi amabili ama-433 kanye nama-866 MHz), alandelwa yi ; izimiso ezifanayo zokusebenza - ukunxenxa ukunikezwa kwamandla ku-chip ngamaza omsakazo nokucubungula isignali engenayo ngokuphuma kolwazi emuva kowamukelayo.
Ngokuvamile, ithegi ye-RFID ibukeka into efana nale: i-substrate, i-antenna, kanye ne-chip ngokwayo.

Kodwa-ke, "indawo" yokusebenzisa lawa mathegi empilweni yansuku zonke ishintshe kakhulu.
Uma ngo-2012 NFC () kwakuyinto engavamile ku-smartphone, okwakungacaci ukuthi ingasetshenziswa kanjani futhi kuphi. Futhi ama-giants anjengoSony, ngokwesibonelo, akhuthaze ngenkuthalo i-NFC ne-RFID njengendlela yokuxhuma amadivayisi (isipika esivela ku-Sony Xperia yokuqala, exhuma ngomlingo ngokuthinta ifoni - Hewu! Okuqukethwe okushaqisayo!) futhi ushintshe izimo (isibonelo, weza ekhaya, waswayipha umaka, ifoni yavula umsindo, ixhunywe ku-WiFi, njll.), okuyinto, ngokubona kwami, yayingathandwa kakhulu.
Kwathi ngo-2019, amavila kuphela angawasebenzisi amakhadi angenantambo (aseyi-NFC efanayo, ubukhulu becala), amafoni anamakhadi abonakalayo (udadewethu, lapho eshintsha ifoni yakhe, wafuna ngenkani i-NFC kuyo) nokunye “ukwenziwa lula” kwempilo okusekelwe. kulobu buchwepheshe. I-RFID isiyingxenye ebalulekile yokuphila kwethu kwansuku zonke: amabhasi alahlwayo, amakhadi okufinyelela emahhovisi amaningi nezinye izakhiwo, izikhwama ezincane ngaphakathi kwezinhlangano (njenge ) “kanye nokunye, njalo njalo, njalo njalo.”
Empeleni, yingakho kunenombolo enkulu kangaka yamathegi, ngayinye ofuna ukuyivula futhi ubone ukuthi yini efihliwe ngaphakathi: i-chip kabani efakiwe? ivikelwe? hlobo luni lwe-antenna?
Kodwa izinto zokuqala kuqala ...
Kwakulezi zingcezu ezincane ze-silicon ezenza umhlaba wethu waba ngendlela esiwazi ngayo namuhla.
Amagama ambalwa mayelana nokuvula amathegi
Ake ngikukhumbuze ukuthi ukuze ufinyelele ku-chip ngokwayo, udinga ukunciphisa umkhiqizo usebenzisa ama-reagents amakhemikhali. Isibonelo, khipha igobolondo (imvamisa ikhadi noma umaka wepulasitiki oyindilinga onothi ngaphakathi), nqamula ngokucophelela i-chip othini, geza i-chip ngokwayo ku-glue/insulator, ngezinye izikhathi khipha izingxenye zothi ezidayiselwe ngokuqinile kumaphedi okuxhumana. , bese ubona kuphela i-chip nesakhiwo sayo.
Ukunciphisa kuwumuzwa onzima
Izinto ezisetshenziselwa ukufaka ama-chips zenze ukuthuthuka okumangalisayo eminyakeni yamuva nje. Ngakolunye uhlangothi, lokhu kwandisa ukuthembeka kokunamathiselwe kwe-chip futhi kwanciphisa inani lamaphutha; ngakolunye uhlangothi, ukumane ubilise i-acetone noma i-sulfuric acid egxilile ukuze kuncibilike noma kushise izinto eziphilayo manje ngeke kugeze i-chip. Kufanele ube yinkimbinkimbi, khetha ingxube yama-acids ukuze ususe izendlalelo ezingadingekile, kodwa ngesikhathi esifanayo ungalimazi i-flame motor ku-metalization ye-chip.
Ubunzima bokunciphisa: lapho i-glue evela ku-chip ayikwazi ukugezwa ngaphansi kwanoma yiziphi izimo ... Lapha nangaphezulu ЛМ - i-laser microscopy, ОМ - i-optical microscopy
Noma kunjalo...
Ngezinye izikhathi, yiqiniso, unenhlanhla encane futhi i-chip, ngisho nesendlalelo sokushisa, iphenduka ihlanzekile, engathinti kakhulu ikhwalithi yesithombe:
I-NB: Ama-asidi agxilile kanye nezincibilikisi kufanele kuphathwe endaweni enomoya omuhle, noma okungcono ngaphandle! Ungazami lokhu ekhaya ekhishini!
Ingxenye ewusizo
Njengoba ngike ngaphawula ekuqaleni kwalesi sihloko, ingxenye ngayinye izokwethula izinhlobo ezihlukene noma amathegi amaningana: ezokuthutha (izithuthi zomphakathi nama-ski pass), evikelekile (ikakhulukazi amakhadi ahlakaniphile), "nsuku zonke" njalonjalo.
Ake siqale namuhla ngamathegi alula angatholakala cishe yonke indawo. Masibabize ngokuthi "amathegi ansuku zonke" ngoba ungabathola cishe yonke indawo: kusukela kunombolo yemarathon ukuya engqungqutheleni nokulethwa kwezimpahla.

Amathegi Ebanga Elide le-UHF
Abafundi abaningi be-Habr bayadlala futhi bayathanda ezemidlalo. Eminyakeni embalwa edlule, kube nomkhuba ozwakalayo wokubamba iqhaza emijahweni eyahlukene, ama-half marathon ngisho nama-marathon. Kwesinye isikhathi ngenxa yendondo .
Imvamisa, ngaphambi kokuqala komcimbi, inombolo yombambi qhaza ikhishwa efakwe amagwebu amancane ezinhlangothini, ngemuva okuthi - ukwethuka kwezinto ezesabekayo - kufihlwe umaka we-RFID owaziwayo. yomcimbi! Akunjalo Empeleni. Njengoba isiqalo senqwaba sisetshenziswa emiqhudelwaneni enjalo, kuyadingeka ukuhlela isikhathi somhlanganyeli ngamunye kusukela ngesikhathi sokuwela umugqa wokuqala kuze kube sekugcineni. Ukugijima ngohlaka olukhethekile ngendlela yokuqalisa nokuqeda amasango, umhlanganyeli ngamunye uqala futhi, ngokufanelekile, amise isitophuwashi esingabonakali.
Amamaki abukeka kanjena:
Njengoba umkhuba ubonisile, ngisho naseSwitzerland kukhona okungenani amathegi amabili asetshenziswa emicimbini yomphakathi enjalo. Zihlukene kokubili kuma-antenna (ngokwejwayelekile, amancane futhi abanzi) kanye nokwakheka kwe-chip. Yiqiniso, kuzo zombili izimo kuyi-chip evamile kakhulu, ngaphandle kokuvikelwa, ngaphandle kwanoma yiziphi izinsimbi namakhwela futhi, ngokusobala, enenkumbulo encane. Futhi, njengoba umkhuba ubonisile, futhi kusuka kulo mkhiqizi - .
Kunzima kimi ukwahlulela ukuthi kukhona yini okurekhodiwe ku-chip; cishe isebenzela ukuhlonza. Uma wazi okwengeziwe, bhala kumazwana!
